If it worked reliably, I would. Clang and __GNUC__ is a perfect
example. Confer: http://www.google.com/search?q=clang+__GNUC__+bug.

I find it easier to pick up OS'es and Compilers (including versions as
required), and work around their personalities. Using OS/Compilers,
I've got code that cross compiles cleanly on Windows, Mac OS, and
Linux using Clang, Comeau, ICC/ICPC, VC++. And the programs are
correct.
